山東(dong)省青州市魯東(dong)機械2.1MW光(guang)伏發電(dian)站(zhan)(zhan)項(xiang)目。彩(cai)鋼瓦屋頂(ding)光(guang)伏發電(dian)站(zhan)(zhan)，已(yi)并網發電(dian)成功！

輸送方式

太陽能光伏發電(dian)(dian)分為獨立光伏發電(dian)(dian)、并網光伏發電(dian)(dian)、分布式光伏發電(dian)(dian)

獨立光伏發電

獨立光伏(fu)發電(dian)系統(tong)也叫離網(wang)光伏(fu)發電(dian)系統(tong)。主要由(you)太陽能電(dian)池(chi)組(zu)件、控制器、蓄(xu)電(dian)池(chi)組(zu)成(cheng)，若(ruo)要為交(jiao)流負(fu)載(zai)供電(dian)，還需要配置交(jiao)流逆變(bian)器。

并網光伏發電

并(bing)網(wang)(wang)光(guang)伏(fu)發電(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)就是(shi)太陽能(neng)組件產生的直(zhi)流電(dian)(dian)(dian)(dian)經過并(bing)網(wang)(wang)逆變器(qi)轉換成符合市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)網(wang)(wang)要求的交(jiao)流電(dian)(dian)(dian)(dian)之后直(zhi)接接入公(gong)共電(dian)(dian)(dian)(dian)網(wang)(wang)。并(bing)網(wang)(wang)光(guang)伏(fu)發電(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)有集中式大(da)(da)型(xing)并(bing)網(wang)(wang)光(guang)伏(fu)電(dian)(dian)(dian)(dian)站一(yi)般都是(shi)國家級(ji)電(dian)(dian)(dian)(dian)站，主(zhu)要特(te)點是(shi)將所發電(dian)(dian)(dian)(dian)能(neng)直(zhi)接輸送到(dao)電(dian)(dian)(dian)(dian)網(wang)(wang)，由電(dian)(dian)(dian)(dian)網(wang)(wang)統(tong)(tong)一(yi)調配向用戶(hu)供電(dian)(dian)(dian)(dian)。但這種電(dian)(dian)(dian)(dian)站投資大(da)(da)、建(jian)(jian)設周期長、占地面(mian)積大(da)(da)，發展(zhan)難度相對較大(da)(da)。而分(fen)散(san)式小(xiao)型(xing)并(bing)網(wang)(wang)光(guang)伏(fu)系(xi)(xi)統(tong)(tong)，特(te)別是(shi)光(guang)伏(fu)建(jian)(jian)筑一(yi)體化發電(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)(tong)，由于投資小(xiao)、建(jian)(jian)設快、占地面(mian)積小(xiao)、政(zheng)策支持力度大(da)(da)等優點，是(shi)并(bing)網(wang)(wang)光(guang)伏(fu)發電(dian)(dian)(dian)(dian)的主(zhu)流。

分布式光伏發電

分布(bu)式(shi)光(guang)伏(fu)發電(dian)系(xi)統，又稱(cheng)分散式(shi)發電(dian)或(huo)(huo)分布(bu)式(shi)供(gong)(gong)能，是指在(zai)用(yong)戶現(xian)場(chang)或(huo)(huo)靠近(jin)用(yong)電(dian)現(xian)場(chang)配置較小的光(guang)伏(fu)發電(dian)供(gong)(gong)電(dian)系(xi)統，以滿(man)足特定用(yong)戶的需求，支持現(xian)存(cun)配電(dian)網(wang)的經濟運(yun)行(xing)，或(huo)(huo)者同時滿(man)足這(zhe)兩(liang)個方面的要求。

　　分布(bu)式光伏發電(dian)(dian)系統的(de)(de)基本設備包(bao)括光伏電(dian)(dian)池(chi)組(zu)件、光伏方陣支架、直(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)、直(zhi)流(liu)(liu)配(pei)電(dian)(dian)柜、并網(wang)逆(ni)變(bian)器(qi)、交流(liu)(liu)配(pei)電(dian)(dian)柜等(deng)設備，另外還有供電(dian)(dian)系統監控裝置(zhi)和環境監測裝置(zhi)。其運行模(mo)式是在(zai)有太(tai)陽(yang)輻射的(de)(de)條件下，光伏發電(dian)(dian)系統的(de)(de)太(tai)陽(yang)能(neng)電(dian)(dian)池(chi)組(zu)件陣列將太(tai)陽(yang)能(neng)轉換輸出的(de)(de)電(dian)(dian)能(neng)，經過直(zhi)流(liu)(liu)匯(hui)流(liu)(liu)箱(xiang)集中送入直(zhi)流(liu)(liu)配(pei)電(dian)(dian)柜，由并網(wang)逆(ni)變(bian)器(qi)逆(ni)變(bian)成(cheng)交流(liu)(liu)電(dian)(dian)供給建(jian)筑自身(shen)負(fu)載，多余或不足(zu)的(de)(de)電(dian)(dian)力通過聯接電(dian)(dian)網(wang)來(lai)調節(jie)。
